 Scientific Name: Hyphodontia nespori

Basionym: Odontia nespori Bres., Ann. Mycol. 18: 43. 1920.

Hyphodontia nespori (Bres.) J. Erikss. & Hjortstam in J. Erikss. & Ryvarden, Cort. N. Eur. 4: 655. 1976.

 Description: Basidiocarp effuse, ± adnate, membranaceous and soft when young, ceraceous and brittle when old, 80-150 μm thick in section (aculei excluded). Hymenial surface Cream Color, Cartridge Buff, or Pale Buff, grandinioid, cracked when old. Aculei rather crowded, sometimes fused, ca. 10 per mm, conical, sometimes apically fimbriate, 80-250 × 100-200 μm. Hyphal system monomitic; hyphae nodose-septate. Subiculum uniform, composed of medullary layer, with rather loose texture when young, much denser when old, especially parts close to subhy-menium; hyphae richly ramified, somewhat interwoven, colorless, distinct, 2.5-4.5 μm diam., with 0.4-0.8 μm thick walls. Hymenial layer with compact texture, thickening when old; hyphae vertical and yellowish. Hymenium and adjacent subhymenium IKI brownish, somewhat CB+. Trama with compactly arranged and yellowish hyphae. Rounded granular crystals common in aculei. Cystidia numerous, more concentrated in aculei, scattered elsewhere, usually apically encrusted, ± capitate, slightly flexuous, 25-50 × 3.5-5.5 μm, thin-walled. Basidia subutriform, 15.5-22.5 × 3.2-4.2 μm, 4-sterigmate. Basidiospores cylindrical or narrowly ellipsoid, smooth, thin-walled, with a minute apiculus, usually containing two or more small oil-drops, (4.3-) 4.7-5.7 (-6) × (2.2-) 2.4-2.8 μm, IKI-, slightly CB+.

 Note: The basidiocarp of this species is variable, ranging from soft and membranaceous when young to ceraceous and brittle when old. In this respect H. nespori is similar to H. lanata. However, H. nespori is recognized by the capitate cystidia, shape of the basidio-spores, and the rounded granular crystals usually abounding in the aculeal region.
